Driving MEX-ZIH

How much bus time from CDMX to Zihuatanejo, please?

I took an overnight from Zihuatanejo to CDMX. It took a bit over 8 hours. And that was before the upgraded autopista was finished. This bus only had a few stops as I remember. I had a hard time sleeping on the bus, though. The sound of snoring was deafening.

That's what earbuds with noise cancellation are for.
Love my Liberty 4 NC earbuds by Soundcore! Also got a pair of their Space Q45 headphones for when there's terrible music at deafening levels playing outside my window.

Yeah, it's still about an 8-hour drive on the luxury direct bus. Nighttime is the best time for taking the bus.
